SPECIFICATION forming part of Letters Patent No. 529,876, dated November 27, 1894.

Application filed June 80, 1894. Serial No. 516,217. (N0 Specimens-l To all whom it may concern: I Be it known that I, J OSEF PATTIGLER, a 7 subject of the Emperor of Austria-Hungary,

hardness and tenacity is required-for various uses, then there are added to the mass ten to res1ding at Vienna, Austria-Hungary, have invented certain new and useful Improve-' ments in Plastic Compositions, of which the' following is a specification. My invention relates to the manufacture of a composition for various purposes .in the to arts.

The principal object of my invention is to. provide a simple, inexpensive, durable and. efiicient compound partaking somewhat'of' the nature of india rubber, but adapted for r many uses other than those-to which india rubber and like products are applicableyvith good effects in the different arts.

My invention consists of a composition consisting of the ingredients and compounded. in substantially the manner hereinafter described and claimed. A

The nature, objects and general scope of my invention will be more fully understood from the following description of one preferred method of compounding the-composition of myinvention with some of the applications thereof in the diflferent arts.

A charge of linseed oil is placed in preferably a steam hea e e e or the like and 3c boiled until bubbles are formed therein,when

iiiidfe are added successively thereto forty parts of Yienna white or caustic. ten parts of lime twentypartso rau 1c cem nt andten parts of glaster of p a ri i an"c'1 after th'e sepa- 5 rate an evera a mix ures of the above ingredients have been made thereto and the mass-has been brought to a more or less consistent mass, sawdust or owdered stone is added 1n such qua%t1t1es as i0 .produce the necessary hardness of structure, and then five to ten parts of soluble lass these ingredients being so ombi'nei'reie' with as to produce an intimate admixture or homo- A geneous compound for various uses in the arts, which will be hereinafter more fully explained. In case -a composition of greater fifteen parts, more or less, of ulverized fire prick uartz: flint ordthe like and which as 50 practlce as emonstrated gives an excellent product.

It may be here remarked that the hereinbefore described composition is especially adapted for molding casts, terra cotta and stucco work, busts and other technical purposes; and is especially adapted on account I of its susceptibility to become yery hard and owing to its water proof nature, for plastics, such as building material, cornices, moldings and as a substitute for caoutchouc, gutta percha, linoleum and for the manufacture of door mats and other somewhat similar articles. The above described composition is water proof and is not inflammable, and while it readily carbonizes, yet in the presence of an intense heator flame, such will have no eifect upon the same.

It will be obvious to those skilled in the art to which my invention appertains, that the proportions of ingredients entering into the composition of the compound hereinbefore described,-may be varied without departing from the spirit of my invention; and hence I do not wish to be understood as limiting myself to the precise proportions of the said materials as mentioned; but i 4 Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

A plastic composition, composed of vege table or mineral oil, Vienna white or caustic, lime ent 'laster gpagisia wdgst and soluble glass, substantially as and for the j purposes set forth. 8 5

In testimony whereof I have hereunto'set my signature in the presence of two subscribing witnesses.
